ABSTRACT:
An aqueous solution of a metal salt solution is converted to the corresponding acid by hydrogen ion substitution in a four compartment electrolytic cell containing three cation permselective membranes or barriers for defining the cell compartments. In one specific embodiment the salt solution initially treated in the intermediate compartment located adjacent to the cathode compartment is further treated by passing into the intermediate compartment located adjacent the anode compartment and thereafter removing the same as the final acid product. Such a flow arrangement prevents or reduces loss of hydrogen or citrate ions into the cathode compartment resulting in an increased acid yield with increased current efficiency.
